Area Forecast Discussion
National Weather Service Northern Indiana
716 PM EDT Thu Sep 21 2017

.SYNOPSIS...
Issued at 114 PM EDT Thu Sep 21 2017

Very warm and dry weather will persist into the middle of next week
as high pressure remains parked over the Great Lakes. Highs will
range from to mid 80s to around 90 with lows in the 60s for the next
several days.

&&

.SHORT TERM...(Tonight and Friday)
Issued at 306 PM EDT Thu Sep 21 2017

Amazing warmth for late September this aftn with upper 80s to low
90s widespread. In addition substantial boundary layer moisture had
resulted in local heat indicies in excess of 100.

Little change going forward with upper ridge parked overhead and
expect a carbon copy of today.

&&

.LONG TERM...(Friday through Wednesday)
Issued at 306 PM EDT Thu Sep 21 2017

Upper ridge peaks Sat near lake SC before drifting off into the
Hudson valley late Sun yet extends broadly westward through the wrn
OH valley. Deep wrn trough is slow to kick ewd given downstream
block between upper ridge and nwd approaching HRCN Maria and
reflected in ewd slowing 12Z consensus solution. Thus significant
cooling looks delayed until Thu. Rain chances relegated to frontal
zone look limited late period owing to upper trough ejecting newd
through the dakotas and poor moisture return and will cap at slight
chance mention at best Wed-Thu.

.AVIATION...(For the 00Z TAFS through 00Z Friday Evening)
Issued at 715 PM EDT Thu Sep 21 2017

VFR through the period as ridging dominates.
